S type tension load cell

S-type load cell is the most common sensor , it is mainly used to measure the tension between the solid and the pressure, general also known as the pull pressure sensor, because it looks like the shape of S.The QH-3 series load cells are customary S-type load cell, the material can be alloy aluminum, alloy steel or stainless steel,with plastic seal protection treatment, easy to install, easy to use, they are suitable for hanging scales, batching scales, machine scales and other electronic measuring force weighing system.

Features:

Load cell is based on the principle that an elastomer (elastic element, sensitive beam)

is elastically deformed by an external force so that the resistance strain gauges (conversion

elements) attached to the surface are deformed along with deformation of the resistance strain

gauge, The value will change (increase or decrease), and then the corresponding measurement

circuit to change this resistance into electrical signals (voltage or current),thus completing

the process of converting external forces into electrical signals.
